The handling of an email to Hillary Clinton from longtime adviser Sidney Blumenthal discovered in a new release of documents is a “smoking gun” violation of national security laws requiring a prison sentence, charges a former military intelligence officer. Clinton forwarded the Aug. 8, 2009, email – clearly marked “Classified” – to a personal, nonsecure email address registered to aide Huma Abedin, huma@clintonemail.com. Abedin then forwarded the message to another personal, nonsecure account, humamabedin@yahoo.com.
